On Air: College students help fight invasive species
Great Lakes Aquatic Invasive Species - Watercraft Inspection - News
Oswego, NY, August 1, 2012 - All summer long, the Department of Environmental Conservation and New York Sea Grant are stationing college students at boat launches around New York with, as heard in this audio clip from WRVO Radio, the mission to stop the spread of invasive species.

The college students are called launch stewards. The $75,000  program is a top priority for the DEC, says Mary Penney of New York Sea Grant, a government coastal cooperative.
Penney supervises the half-dozen stewards in central New York and says the program is intended to make sure invasive species in one lake don't spread into others by hitchhiking on boats.
The steward's job - from May to September - is to educate boaters about invasive species, as well as assist in boat inspections. They'll be on the lookout for plants like hydrilla, or water thyme, that can wreak havoc on native ecosystems.
Plants are known to catch in propellers, but steward Nick Spera says they sometimes hide where you wouldn't expect.
"Most of it, actually, you see on the trailer, not necessarily the boat. The boat doesn't really carry too much. It's the trailer from the site to site. The wheels and the axle -- and you'll pull them out and you won't even notice them because they are underneath," said Spera.
Of particular concern is hydrilla. The Asian plant's aggressive growth is known for choking out native wildlife -- but also for making boating and fishing almost impossible. It was discovered in the Cayuga Lake inlet last fall.
Steward Shelby Persons says she's especially alert to the threat.
"It's definitely scary to meet someone who’s been to Cayuga Inlet. You pay more attention to their boat and make sure there's no hydrilla," said Persons.
So far, it seems to be working. There are no reports of hydrilla taking root in any other lakes. Stewards say they spend most of their time on other plants, like water chestnut and Eurasian water milfoil. The stewards are also gathering data on the species they find. Those reports are contributed to www.imapinvasives.org so that the public can go online and track the spread of non-native species.
